FLOOR CONSTRUCTION.

Specification of Letters Patent. Patented June 15, 1&20.

' Application filed March '17, 1917. Serial No. 155,427.

To all whom it may concern: Be it known that 1, CHARLES \VHITNEYSTEVENS, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented new and usefulImprovements in Floor Constructions, of which the following is a full,clear, concise, and exact description, reference being had to theaccompanying drawing, forming a part of this specification. My inventionrelates to floor constructions. 1

One of the objects of my invention is to provide animproved form ofsound-deadening floor construction. Further objects will appear from thedetailed description to follow and from the appended claims.

In the drawings, in which an embodiment of my invention is shown- Figure1 is a perspective view of part of a room showing my improved floorconstruction' Fig. 2 is a perspective View of one of the cushioningsupporting brackets for the nailing strips; and I Fig. 3 is afragmentary side elevation of part of the cushioning support.

Referring now to the drawings in detail, the floor construction showncomprises a rough flooring 10 supported by joists underneath it, aplurality of cushioning supports 11 resting on the rough floor 10, aplnrahty of nailing strips 12 resting on the cushlonlng supports 11, anda finishing floor 13 secured to and supported by the nailing strips 12.

The cushioning supports are placed about eighteen inches apart along thenailing strips, and the nailing strips themselves are about sixteeninches apart.

Each of the cushioning supports 11 comprises a sheet-meta] base portion14 which rests on the rough flooring 10, an L-shaped sheet-metal clip 15one leg 16 of which is secured to the base 14 by means of rivets17, andthe other leg 18 of which extends upwardly alongside the side face ofthe nailing strip, and a bent sheet-metal clip 19 having an L-shapedportion 20 shaped to conform to the L-shaped leg 21 of the base 14, anda portion 22 extending upwardly alongside the other side face of thenailing strip 12. Both side faces of the nailing strip 12 are made toslope downwardly and outwardly, and the upwardly-extending portions 18and 22 are shaped so as to overhang the sloping side faces of thenailing strip to hold the strip down. This tends to prevent warping ofthe finishing floor. A pad or cushion 23 of cattle hair, sea grass, orthe like, is secured to the support 11. This pad has a horizontalportion 24 between the horizontal.

sheetmetal portion or leg 16 and the bottom face of the nailing strip,an upwardly-extending portion 24 between the upwardlyextendingsheet-metal portion 18 andone of the sloping side faces of the nailingstrip, and an upwardly-extending portion 25 between theupwardly-extending sheet-metal portion 22 and the other sloping sideface of the nailing strip.

On account of the cushioning supports 11 thereis no connection betweenthe finishing flooring 13 and the rough flooring 10 except through thepads 23. The bases 14 are made high enough so that the pipes 26- for thegas and electric wiring can pass beneath the nailing strips 12 withoutcoming in contact therewith.

In constructing the flooring two of the cushioning supports 11 may beplaced in position one at each end of the nailing strips, and thesesupports may be secured to the rough flooring and the nailing strips maybe secured to the supports. The intermediate cushioning supports maythen be placed in position by slipping the base portion 14 and thehorizontal portion 16 ofthe L-sh'aped clip 15 underneath the nailingstrip with the in position. The clip 19 may be secured in,

position by a headed fastener extending through an opening 27 in theportion 20 of the clip and through a corresponding opening in the base14.

The sheet metal parts of the support 11 are so shaped that they may bereadily formed in ms. I claim as new and desire to secure by LettersPatent:

' 1. A floor construction comprising a lower floor, a plurality ofcushioning supports bearing on said lower floor, nailing stripssupported by said cushioning supports and having their upper facesexposed and lying in a plane above said supports, and a finishing floorsecured to said nailing strips, each of said supports comprising aportion overhanging a portion of the nailing strip for "holding it downwhereby said finishing fioor will be restricted to a maximum movementmeasured by the compression of the cushioning supports.

2. A floor construction comprising a lower floor, a plurality ofcushioning supports bearing on said lower floor, nailing stripssupported by said cushioning supports and having their upper facesexposed and lying bearin in a plane above said support, and a finishingfloor secured to said nailing strips, each of said supports comprising aportion overhanging a portion of the nailing strip for holding it downand cushioning means between said overhanging portion and said nailingstrip whereby said finishing floor will be restricted to a maximummovement measured by the compression of the cushioning supports.

3. A floor construction comprising a lower floor, a pluralit ofcushioning supports bearing on said ower fioor, nailing strips supportedby said cushioning supports andhavin their upper faces exposed and lyingin a p ane above said supports, and a finishing floor secured tosaid-nailing strips, said nailing strips each having an outwardly anddownwardly sloping side, and said supports each havin a portionoverhanging and against said inclined side for holding sa1d nailingstrips down whereby said finishing floor will be restricted to a maxi,-mum movement measured by the compression of the cushioning supports.

4. A floor construction comprising a lower floor, nailing strips abovesaid lower floor, eachv nailing strip having both of its side facessloping downwardly and outwardly,-a finishing floor resting upon andsecured to said nailing strips, and cushioning means supported by saidlower floor for supporting said nailing strips comprising portionsoverhanging and bearing against both sloping side faces of each of saidnailing'strips for I holding said strips down whereby said nailingstrips will be restricted to a maximum movement measured by thecompression of the cushlomng means. 1

5. A floor construction comprising a lower a floor, nalling strips abovesaid lower floor,

each nailing strip having both of its side for holding said strips downand cushioning means between said overhanging portions and sloping sideswhereby said nailing strips Will be restricted to a maximum movementmeasured by the compression of the cushioning means.

6. A floor construction comprising a lower floor, 'a plurality ofcushioning supports bearing on said lower floor, nailing stripssupported by said cushioning supports, a finishing floor resting uponand secured to said nailing strips, each of said supports com prising anL-shaped sheet-metal member having a horizontal leg extending underneaththe nailing strip and the other le extending up alongside the side face0 the nailing strip, cushioning means between said Q L-shaped member andthe bottom and sides of the nailing strip, and means comprising aninterposed cushioning means cooperating with said L-shaped member anditsassociated cushioning pad to hold said strip down, whereby said stripwillbe restricted to a maximum movement measured by'the com pression ofthe cushioning means.v
